IMPROIVEM ENT' \l N SULKY-PLOWS.

Specification forming part of Letters Patent No. 219,800, datedSeptember 23, 1879; application filed April 28, 1879.

To all whom it may concern:

Be it known that we, BYRON (l. BRADLEY and CHARLES A. HAGUE, of Chicago,Cook county, State of Illinois, have invented a new and usefulImprovement in Sulky-Plows, of which the following is afull description,reference being had to the accompanying drawings, in which Figure l is avertical section taken at line a; of Fig. 3. Fig. 2 is a detail,'and isa vertical section of theparts shown, taken at y of Fig. 3,1ooking tothe right. Fig. 3 is a plan or top view of the parts represented. Fig. 4is a rear elevation of the parts represented. Fig. 5 is an enlargeddetail in section.

The object of this invention is to provide improved devices by the useof which the plow can be raised out of the ground while in motion, andby the power of the team, which we accomplish by means ofa-friction-band upon the hub, or an attachment thereto of one of thewheels, which band is connected with the crank-axle, which carries theplow, by means of a rod or bar, and can be tightened upon'the hub by theaction of the driver, when desired,

the parts being so constructed that when said band is tightened upon thehub the band will rotate for the time being with the hub, and, throughthe rod or bar which connects it with the crank-axle, will cause theaxle to rotate with the hubs, lifting the plow out of the ground. Whenraised sufficiently the axle engages with a hook, and the friction-bandcan be released.

In the drawings, A represents a plow, which is hinged upon a crank-axle,B, which axle carries the wheels 0 D. a is an angle-iron, secured to theframe, to which iron the tongue is secured. Y

E may be regarded as an extension on the inside of the hub of the wheelD. As shown, it is made separate from the hub, and is connectedtherewith by a pin 5 but in practice any other suitable means may beused for connecting extension E to the hub F.

"b is a fixed sleeve, suitably secured to the frame G, to furnish alarger axle for the extension E. c is a friction-band, which, exceptwhen tightened by the operator, loosely encircles the inner end, d, ofthe extension E, which is adapted to receive such band. The two ends ofthis band 0 are connected to a short bar on lever, e, as shown in F' 2,and in such manner that, through the movement of such lever e, the band0 can be tightened pon the part d. This can conveniently be done bymeans of a foot-lever, f, located so as to be easily reached by the footof the driver, and a lever, g, con nected with the foot-lever and aconnecting bar or rod, h, one end of which is pivoted to the lower endof lever e, and the other end to the lower end of lever g.

'iiS a metal bar, one end of which is con nected with the friction-bandc, and the other to the crank-axle B at a point some distance from thecenter of rotation of such axle.

H is a hook, pivoted to the frame and an ranged so as to engage with andhold up the axle when sufficiently elevated. lever, by means of whichthe driver can raise the plow, if desired, as usual.

In Fig. 1 we have shown the several parts as they are when the plow andwheels are standing on a level and not in use; but when in actual usethe front end of the beam will be somewhat raised, and will be incontact with some fixed part connected with the frame, as usual.

The operation of our improvement is, as follows: If the driver pushesthe upperend of the foot-lever forward, the friction-band-e will betightened upon the part d of the extension E through the levers g e andbar h, and when the friction between the band and the exten sion issufficient the band will move with the extension, and, carrying the bari forward with it, the axle will rotate with the hubs, and the crankpart of the axle will be elevated, lifting the plow out of the ground,itbeing understood, of course, that while this is being done the team andplow are in motion. When the plow has been sufficiently raisedthe hook Hwill engage with the axle and hold it up until the hook is released.After the hook has engaged with the axle the driver will release thefootlever, when the band will again be loose upon the extension.

The parts which we have not described are constructed in the usualmanner.

The inside of the hub might be adapted to receive the band 0, theextension E being dispensed with, or being cast with the hub, but IP'IJENT OFFICE;

I. is a handit is much easier to make the extension E separate from thehub. The band might be applied to a collar secured to the hub, or uponthe inside of the wheel, and the result would be the same. When theextension is used it would not be desirable to use the collar.

A chain might be used to connect the friction-band with the axle; butthe bar 1' is better, because a chain might kink.

We do not limit ourselves to the exact construction and arrangement ofthe friction-band and operating levers and bar shown and described, asvarious modifications of the levers and connections might be made.

What we claim as new, and desire to secure by Letters Patent, is asfollows:

1. In a sulky-plow, the friction-band c and a connecting bar or piece,t, in combination with the crank-axle and one of the hubs, or anextension thereof, for the purpose of raising the plow out of theground, substantially as specified.

2. In a sulky-plow, the friction-band c and connecting-piece t, and thelevers e f g and bar h, in combination with the axle B and one of thehubs, or an extension thereof, substantially as and for the purposesspecified.
